[2] It is evident from the explanations which have been given that the joining together of good and truths which leads to regeneration is a process that grows more and more interior; that is, truths are joined step by step more interiorly to good. For the object of regeneration is that the internal man may be joined to the external, and so the spiritual man be joined to the natural through the rational Unless the two are joined together no regeneration is accomplished. Nor can that joining together be effected until good has first been joined to the truths within the natural; for the natural has to exist as the underlying groundwork, and things within the natural have to exist in correspondence with those above them. This is the reason why, when the natural is being regenerated, the joining together of good and truths becomes step by step more interior; for the spiritual first joins itself to the things that are inmost in the natural, and after that through these to those that are more exterior. Nor can man's internal join itself to his external unless the truth within that external becomes the good of truth, that is, becomes truth in will and action, 4337. Only then can they be joined together, for the Lord flows into a person through his internal man, especially through the good there. The good there is able to be joined to the good in the external man, but not directly to the truth

[3] From this it becomes clear that the truth residing with man must first of all become truth in will and action, that is, become the good of truth, before the joining together of the rational and the natural, or of the internal man and the external, can come about. But in what way truth becomes the good of truth may be clear to anyone who gives his attention to it. Every Divine truth is related to the following two commandments: Love God above all things, and love your neighbour as yourself. These two commandments are the base from which truths are derived, the reason why truths exist, and the end to which truths lead - immediately or remotely. Therefore when truths are translated into action they are introduced step by step into their beginning and into their end, that is to say, into charity towards the neighbour and love to the Lord, and as a consequence truth becomes the good which is called the good of truth. Once truth becomes such it is able to be joined to the internal man, a conjunction which becomes step by step more interior as truths that are more interior are implanted within that good. Action comes first, then the desire for it in the person's will follows. For when a person is led by his understanding to carry out any action, he is at length led by his will to do it, till at last he has taken it on as an action performed habitually. When this point is reached it is introduced into the rational or internal man; and once it has been introduced, truth is no longer that which motivates him when he does a good action but good. For now he begins to feel within it something of what is blessed and so to speak of heaven. This remains with him after death, and by means of it the Lord raises him up to heaven.
